DESCRIPTION OF THE PREFERRED EMBODIMENTS

A vehicle vision system and/or driver assist system and/or object detection system and/or alert system operates to capture images exterior of the vehicle and may process the captured image data to display images and to detect objects at or near the vehicle and in the predicted path of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a rearward direction. The vision system includes an image processor or image processing system that is operable to receive image data from one or more cameras and provide an output to a display device for displaying images representative of the captured image data. Optionally, the vision system may provide a top down or bird's eye or surround view display and may provide a displayed image that is representative of the subject vehicle, and optionally with the displayed image being customized to at least partially correspond to the actual subject vehicle.

Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle 10 includes an imaging system or vision system 12 that includes at least one exterior facing imaging sensor or camera, such as a rearward facing imaging sensor or camera 14 a (and the system may optionally include multiple exterior facing imaging sensors or cameras, such as a forwardly facing camera 14 b at the front (or at the windshield) of the vehicle, and a sidewardly/rearwardly facing camera 14 c, 14 d at respective sides of the vehicle), which captures images exterior of the vehicle, with the camera having a lens for focusing images at or onto an imaging array or imaging plane or imager of the camera (FIG. 1). The vision system 12 includes a control or electronic control unit (ECU) or processor 18 that is operable to process image data captured by the cameras and may provide displayed images at a display device 16 for viewing by the driver of the vehicle (although shown in FIG. 1 as being part of or incorporated in or at an interior rearview mirror assembly 20 of the vehicle, the control and/or the display device may be disposed elsewhere at or in the vehicle). The data transfer or signal communication from the camera to the ECU may comprise any suitable data or communication link, such as a vehicle network bus or the like of the equipped vehicle.

Navigation/Networked Smart Park:

The present invention provides a parking assist system or smart park system that is operable to assist the driver of a vehicle equipped with the parking assist system to find a parking space at or near the current location of the equipped vehicle. Such a system may empower or enable the vehicle system (which preferably includes a display to display the various found parking space locations to the driver) to assist the driver in finding an urban parking space.

Typically, a driver must circle through a city until he or she is lucky enough to find an available parking spot. This often can be very time consuming and frustrating to the driver of the vehicle. The system of the present invention avoids such frustration by, such as responsive to a user input (such as a button or switch or voice command or the like), displaying or otherwise conveying to the driver where a nearby parking space or spaces may be located.

The parking assist system of the present invention uses sensors and a networked database to make this process more efficient. For example, the system may, with the inclusion of a navigation system, such as a GPS or the like (such as an output of a navigation system that is indicative of the current location of the vehicle), the parking assist system can record the parking space or lot locations that were previously used by the driver or vehicle or system (such as where the vehicle was parked a previous time or several times that the parking assist system was used or actuated). Optionally, with the inclusion of sensor(s), such as a rear or front-facing camera, that are operable to detect other parked vehicles, the system can record the frequency of parked cars in an area, and thus may determine or estimate the likelihood of finding an empty space or may provide a hierarchy of potential parking spaces in an order of likely availability.

Optionally, with the inclusion of a wireless network, such as 802.11p network or the like, a database within the vehicle or at a remote server can record any other nearby vehicles that have recently used the parking assist system (such as other vehicles similarly equipped with the parking assist system of the present invention or the like) and share this to the parking assist system of the subject vehicle and other similar parking assist systems. If Internet access is available, available parking spaces or lots can be cross referenced with all other data (and the location of available spaces may be communicated to the driver of the vehicle to further enhance the driver's ability to readily find an available parking space).

As shown in FIG. 2, the display may display a map image showing the current location of the equipped vehicle and various parking lots at or near a threshold distance of the vehicle. In the illustrated embodiment, the displayed image shows the parking spaces ahead of the vehicle in the current direction of travel of the vehicle, but the display may (such as responsive to a user input or selection) display parking spaces behind the vehicle or in any direction relative to the vehicle.

Optionally, and such as shown in FIG. 2, the display may highlight the parking spaces in accordance with prior parking data or other vehicle parking data. For example, the system may display locations where the driver of the subject vehicle has previously parked (such as where the equipped vehicle was parked over the previous three months or any other suitable prior time period). Optionally, the system may receive data from other parking assist systems and/or a remote server, and may display parking locations that have been previously used by other vehicles, such as by other vehicles similarly equipped with a parking assist system of the present invention. The highlighting of the historic parking data for the equipped or subject vehicle may be displayed as a different color than the highlighting of the historic or current parking data of other similarly equipped vehicles. Optionally, the displayed image may include the price for parking at the displayed locations so that the driver can make a decision as to which lot may be preferred based on the relative location of the parking lot or space to the equipped vehicle and cost to park at that parking lot or space.

Optionally, for parking lots that are full, the parking assist system may receive a communication to that effect and may remove that parking lot or structure from the display or display that parking lot or structure as unavailable. It is envisioned that, in areas that use automated parking meters, that information provided by such systems may be received by the parking assist system of the present invention, and currently available street side parking spaces may also be displayed to the driver of the equipped vehicle (optionally such parking space availability information or data may be derived from images captured by traffic cameras or building security cameras and/or the like). Any of the above information can be displayed to the driver on command (or optionally may be automatically displayed in response to the type of driving by the driver when the driving behavior is indicative of someone looking for a parking space).

Thus, and with reference to FIG. 3, when a driver activates the parking assist system of the present invention, the system collects data from vehicle sensors (such as cameras or the like), sensors external of the vehicle (such as traffic cameras or the like), internal databases of the vehicle or parking assist system, and/or external databases (such as provided or accessed via a telematics system of the vehicle and/or a remote server connection or the like). The parking assist system then displays the nearby and/or available parking lots to the driver of the equipped vehicle. The driver then may select a preferred or nearby location and park in an available space at the selected location. The parking assist system may record the parked location (such as for future reference) and/or may transmit the parking data (such as for use by other vehicles equipped with parking assist systems) before the vehicle is turned off.

The parking system may utilize aspects of the systems described in U.S. provisional application Ser. No. 62/006,391, filed Jun. 2, 2014, and/or U.S. patent application Ser. No. 14/169,329, filed Jan. 31, 2014 and published Aug. 7, 2014 as U.S. Publication No. US-2014-0218529, Ser. No. 13/660,306, filed Oct. 25, 2012, now U.S. Pat. No. 9,146,898, and/or International Publication No. WO 2013/109869, which are all hereby incorporated herein by reference in their entireties.

Networked Alarm and Tracking:

The present invention also provides a security or alert system that detects a vehicle break in or other action at the vehicle (such as when the vehicle is parked) and provides a communication or alert to one or more of the owner of the vehicle, systems of other vehicles, local authorities and/or the like. The security system is particularly suited for networked vehicles to enhance the response to intrusion and vandalism of one of the networked vehicles.

Currently, if a criminal acts on a vehicle, then only the electronics or systems or accessories that are in the acted-on vehicle itself may sound an alarm or attempt to record the perpetrator. There may not be any nearby security cameras. The present invention provides for automatic communication of the detected criminal act to other vehicles and/or systems to enhance the alert and/or detection of the criminal act.

The security system of the present invention may use a communication network, such as a wireless communication network, to communicate data pertaining to the detection of a break-in or impact or the like at the equipped vehicle. With the inclusion of a wireless network, systems of nearby vehicles can respond to criminal acts as well. For example, responsive to receipt of a communication derived from the vehicle that is acted on (such as a detection of a vehicle break in or impact at the vehicle or the like), systems of nearby vehicles may sound the respective vehicle alarms, and/or may lock the respective vehicle doors. Such responses are suited for other nearby parked vehicles, which may have their respective security systems running in a sleep mode until the communication from the other system(s) is/are received.

Optionally, responsive to receipt of a communication derived from the vehicle that is acted on, the drivers of nearby similarly equipped vehicles may be alerted as to the where the crime is occurring. Optionally, with the inclusion of internet access or other wireless communication links, the owner of the acted on vehicle may be notified (such as via a text message or automated phone call to the owner's cell phone or the like) and/or the local authorities may be alerted to the occurrence of the detected act. Optionally, responsive to receipt of a communication derived from the vehicle that is acted on, the vision systems of nearby vehicles may activate their sensor or sensors, such as surround-view cameras or the like, to capture image data at and around the nearby vehicles, whereby the captured image data may be recorded by the systems of the nearby vehicles and/or may be transmitted by the systems of the nearby vehicles (such as to the system of the acted on vehicle for future reference or such as to a remote server or such as to the local authorities or the like).

As can be seen with reference to FIGS. 4 and 5, when the equipped or subject vehicle is parked, the vehicle's security system is active and the communication network for the security system is also active. When a criminal act is detected (or a potential criminal act that the system determines is indicative of a break in or vandalism or collision impact at the subject vehicle), the subject vehicle reacts to the determined act. For example, the subject vehicle's system or systems may capture image data of the surrounding area and/or interior cabin of the vehicle and/or may activate the vehicle alarm system (such as by utilizing aspects of the systems described in U.S. patent application Ser. No. 14/169,329, filed Jan. 31, 2014 and published Aug. 7, 2014 as U.S. Publication No. US-2014-0218529, which is hereby incorporated herein by reference in its entirety). The security system of the subject or acted on vehicle also transmits data or information pertaining to the determined act, such as via a wireless communication that may be received by nearby vehicles (such as via a short range wireless communication protocol) and/or by a remote server and/or the local authorities or the like (such as via a long range wireless communication or internet connection or cellular or satellite communication or the like). Responsive to receipt of such data or information, other systems of nearby vehicles react and may transmit additional data or information (such as video images or the like) and/or may retransmit the received data or information to other nearby vehicles (such as vehicles that may have been out of a short range transmission of the subject or acted on vehicle but within range of the short range transmission by the nearby vehicle). Also, responsive to receipt of such data or information, other nearby camera systems may be activated (such as building security cameras or the like) and/or the local authorities may be notified of the potential criminal act and/or the owner of the vehicle may be notified of the potential criminal act.

Thus, the present invention provides a security system that, responsive to a detection of a potential break in at a parked equipped vehicle, may alert other nearby vehicles and/or the vehicle owner and/or the local authorities of the break in. The other vehicle systems may then generate alarms or lock their doors or the like to deter the perpetrator from future action, and/or the other vehicle systems may actuate their cameras or sensors to enhance image capture of the nearby area to assist the authorities in identifying the perpetrator. The present invention thus, responsive to such a detection, causes other nearby vehicles to react accordingly to mitigate the criminal threat. This is similar or analogous to how a bee sting leaves a banana-like odor which compels other bees to react against a threat.

The camera or sensor may comprise any suitable camera or sensor. Optionally, the camera may comprise a “smart camera” that includes the imaging sensor array and associated circuitry and image processing circuitry and electrical connectors and the like as part of a camera module, such as by utilizing aspects of the vision systems described in International Publication Nos. WO 2013/081984 and/or WO 2013/081985, which are hereby incorporated herein by reference in their entireties.

The system includes an image processor operable to process image data captured by the camera or cameras, such as for detecting objects or other vehicles or pedestrians or the like in the field of view of one or more of the cameras. For example, the image processor may comprise an EyeQ2 or EyeQ3 image processing chip available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and may include object detection software (such as the types described in U.S. Pat. Nos. 7,855,755; 7,720,580 and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver's awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle.

The vehicle may include any type of sensor or sensors, such as imaging sensors or radar sensors or lidar sensors or ladar sensors or ultrasonic sensors or the like. The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, a two dimensional array of a plurality of photosensor elements arranged in at least 640 columns and 480 rows (at least a 640×480 imaging array, such as a megapixel imaging array or the like), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. Preferably, the imaging array has at least 300,000 photosensor elements or pixels, more preferably at least 500,000 photosensor elements or pixels and more preferably at least 1 million photosensor elements or pixels. The imaging array may capture color image data, such as via spectral filtering at the array, such as via an RGB (red, green and blue) filter or via a red/red complement filter or such as via an RCC (red, clear, clear) filter or the like. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data.

For example, the vision system and/or processing and/or camera and/or circuitry may utilize aspects described in U.S. Pat. Nos. 7,005,974; 5,760,962; 5,877,897; 5,796,094; 5,949,331; 6,222,447; 6,302,545; 6,396,397; 6,498,620; 6,523,964; 6,611,202; 6,201,642; 6,690,268; 6,717,610; 6,757,109; 6,802,617; 6,806,452; 6,822,563; 6,891,563; 6,946,978; 7,859,565; 5,550,677; 5,670,935; 6,636,258; 7,145,519; 7,161,616; 7,230,640; 7,248,283; 7,295,229; 7,301,466; 7,592,928; 7,881,496; 7,720,580; 7,038,577; 6,882,287; 5,929,786 and/or 5,786,772, and/or International Publication Nos.
